Check out this great online tool for teachers called Canvas. http://www.instructure.com/ . I have been using it with some of my students and it is great!
"Canvas gives teachers the tools they need to not just manage their students, but also to lead a collaborative learning experience. The interface is uncluttered and efficient, with the options teachers need to customize their teaching environment." (Source: Instructure site)
